Unable to find new print head for Pro9000 MK2

[palombian]

I have also had a couple of Canon chips go bad. It is a rare occurrence, but it can happen. When I inserted the cartridge in the printer, the red light came on as normally, but when I closed the lid the printer rejected the cartridge. Only another cartridge with another chip was accepted. Maybe the chip was damaged by a resetter running low on battery, so garbled data was written to the chip?. The damaged chip behaved normally when resat, a short flash, pause and finally a steady light, but it was still rejected by the printer after a new reset.

Same behaviour with a PGI-9 cartridge, with the correct USB powered resetter.
Maybe no coincidence it was the MBK, the one that could not be reset before.

I only had two OEM chip failures on the PGl- 9 carts both were the cyan chips (CLl-8 chip rebadged), sometimes I find by using (The wrong) another resetter to reset the chip it can bring a failed chip back to life..
